Hey there! I've been a long-time follower and fan, so when you started posting Pokemon stuff on your dA again I was quite excited, and it's great to see you back here. :>
Of your recent drawings, I rather like Mewtwoss - unlike Mewtwo's official alternate form, I think it retains a lot of what makes Mewtwo look tough and cool with all those hard lines, and not too streamlined with all the little bulges, like on his hips and feet. Very cool!
Though I'm not a fan of your zen form (I don't like big, bulky Pokemon very much), I think your speed form is quite neat, keeping those lines and points and purple bits.
Also, while I'm still not jiving with Mewtwo's official form, I like the personal touches you give it - it really makes it your style, which I've always enjoyed, and I rather like the design more as a result. I especially like that while you still kept it "young," you didn't keep it too chibi (a failing I feel with the new design). I also like the little things you did, like repositioning the horns to look more like Mewtwo's, and making his fingers and toes more like real appendages than little sausages. Overall, I just really prefer your take on the design (even without changing the position of the tail) and kind of wish it was the official one, haha.
On a random note, I'm also unsure if I agree with you that Mewtwo will become "closer to Mew" in the movie, but we'll see. :> either way, it's great having you back, and I can honestly say I sincerely look forward to seeing more fanart (especially Mewtwo fanart) from you in the future. ^^
