I ended up watching a lot of MOC (my own creation) videos on Youtube and decided I'd like to try designing a few, but after checking out Pick a Brick or Bricklink, so many of the better or more interesting pieces are too pricey to buy in bulk, at least for a beginner unsure of a specific design.
So for practise I picked up a couple of Creator 11032 sets I found randomly in my local supermarket for £25 each down from £63, each set has 1500 varied pieces, that while only has 8 different colours they do give enough for a few designs. I also like the fact that 8 colour restriction resembles some early 8 bit computer colour restrictions. Two of the colours were great beach and sea colours, and with loads of rounded blue pieces in the set I was inspired by The Great Wave build to make lighthouse island MOCs with some detailed, textured water but on a micro scale.
Fairly happy with both as different takes on the idea with also them being sturdy enough to handle, but mostly intended for small display pieces. I definitely prefer the textured water bases to flat blue baseplates which I don't have anyway.
I then made a couple of mini jet MOCs out of the same set with there still being many pieces left over from only one of the opened sets to make other MOCS, though I have used a lot of the more interesting pieces, I still have a complete unopened set of 1500 pieces to use as well.
Definitely a lot of fun and more true to how I used to play Lego as a kid, I think I may design some more detailed MOCs using Lego Studio as it can link with Bricklink and order all the bits you need for it as well as make instructions.
