Firstly let me say I'm very impressed. I've really let my photography wane in recent months and I've my motivation. This little lot has made me realise once again how much there is out there to shoot, so thanks for that. I have to say I like your style and I'm impressed with these images.
So take it as read that I like your work. These are merely my thoughts on each image and what does and doesn't work for me.
1. Very nice shot, slightly spooky and has an ethereal quality to it that works very well. Only downsides are the vignetting in the top corners and the bright object slap bang in the centre of the frame. Not sure if this is intentional but it's a bit off-putting for me.
2. Top half is a great little macro but the bottom half is too gaudy and overpowering. I'd prefer to see a little more detail, a lot more web and less yellow.
3. Great shot, really like this one. Can't stop looking at it. Must... stop... looking. Would make a great poster/canvas.
4. Another lovely landscape shot here, but I feel the crop on the RHS is a bit harsh. My eye keeps getting dragged off to the right and the shot feels a bit unbalanced. Is the wisp of blue/green in the top right intentional or a result of the PP?
5. Not sure about this one. I like the idea but I don't like the shot. It's a good experimental piece though.
6. A bit plain and boring but I understand you have a reason for including.
7. Bit too stark for my liking. Not sure if that's the intention but I'd prefer to see some texture and variance of shade. I'd certainly like to see it in colour.
8. Nice macro but slightly distracting to look at. Firstly my eye gets pulled away from the flower by the white patch in the top left, then I notice the yellow in the bottom left and then I notice the half-in-focus leaf just under the flower. I'd prefer to see a more detailed study of the flower itself - which is actually a rather good shot. I could look at the flower for ages and not get bored.
9. I like the subject matter and I like the style but I think the focal point needs to be on the spiky part of the flower rather than the petals closest to us. When I'm shooting flower macros I try to find a plant with no damage (or as little as possible) so it looks 'perfect' and I'm afraid I find the damage a bit distracting. A little bit of work in PS would clean this one up nicely if you wanted to - but you might be going for a different feel with your shot!
10. I like this as an image - very striking and certainly grabs your attention. Only thing is that the longer I look at it the more I have to look away from the sun and I notice the large expanse of dark at the bottom. Maybe a tighter crop? I have to say I'm undecided about this one.
11. Yep, that's a lovely picture. Very restful and chilled. Maybe it's just my monitor but there doesn't appear to be a lot of detail in the rocks - it's almost a silhouette but not quite and I'd like to see it go definitely one way or the other. I'd like to see the left of the photo cropped to remove the tree - if that is a tree - and concentrate on the building.
12. Nice shot but not a lot of detail there. There does seem to be something poking out of the horizon that could give some interest to the shot - maybe a bit more PP to bring that out? Lovely colours though.
13. Cracking shot, probably the best of the lot for me. Another one I can't stop looking at. Crazy, just crazy.
14. More my cup of tea this one and a very good macro. Might be my eyes but I can't see a focus point, which for my money should be right on the very ends of the stamens and nothing more. Can see this on a canvas or used commercially.
15. Definitely the odd one out. A nothing pic compared to the others, but I appreciate you have your reasons for showing.
PS. I see you have a IR modified 5D - how does that work then?
