I saw you requested a critique, so here one is!
I love the way you did this drawing, I know normally you like to use your markers, and yes I have seen your sketches! I really love the shading you did on this picture, it's not easy! Heck, I can't do it that good! One thing I did notice however, not to be rude, but this is a critique lol , is that Doctor Whoove's facial expression is very limited, personally I think he should be frowning, maybe looking down at himself with horror, like "oh no! Not now, not again!" And also, the shiny gold dust stuff, I dunno what it's called, but the stuff that shoots from his body, I can't see it all that well, I feel that maybe I should be kinda overtaking his body already, not fully, but sorta swirling around him in a way, coming up from his hooves and encircling his body a little like a wreath, not being attracted to him, but just floating upwards if you know what I mean. Overall, I think this work was amazing and just as brilliant and beautiful as any piece I've seen out of you, it really captures a moment in time in a way instead of like "oh it's a picture of blah" this is "this is happening at this time and blah is doing this and it's making blah" not necessarily that in this picture but you know what I mean.
thanks and at this time in the regeneration he only has a faint glow of regeneration energy around his hands well hooves in this case and some being breathed out............. I did this at play practice and my camera was being dumb
