No, they’re not bad. But you did use Sugimori’s drawings as a reference. Though the sparkles around Mew are cute.
But just wish your hand wasn’t in the picture, it’s very distracting. Don’t include stuff like the background and your hand…just lay the drawing on a white surface.
Also, ripping the paper = bad idea. Now it looks trashy, like you just picked up the paper off the ground and started drawing on it.
What's with the gray stuff below Celebi? Are they erase marks or were they done on purpose? Because they don't really fit in too well (other than making the pic more dirty).
So anyways, the drawing is fine, it's just the stuff you did to it that makes it feel less than adequate.
