They have size, but lack definition - but it depends what you're after. They don't look skinny for your height.
Prepare to drop a lot of size leaning them out. My leg measurement drops massively when I'm leaner. Not bad if you've never really trained legs directly though!
I know what legs look like without fat only way I will know is getting that way. I know their is a lot of power in them, get the base right everything else will flow
I always get commented on how big they are, never worked on them, nothing more than my upper body, slow me down in running but the power is great, football shots, cycling power, downside from them is stamina.
