Depth and blending, as mentioned. Btw. the yoshi one is great, I like it, could need some more adjustement layeres but yoshi ruleZ!
I actually like the Yoshi V2 better than the other ones, good job because you made it vibrant while using a grungy background
Haha, Sweet. Still jammin that awesome style I see. You've become a master of it. ^_^ It's also good to see you stepping out into some newer styles too. Keep up the good work.
