Thanks for your comments. You're right. It does look like it's made out of something more solid than just fluffy cloud material :-) I guess it's because of the colour choise.
I will not fix it in this piece because it's old, but I will keep it in mind for future works. Thanks!
I agree with a lot of the people here. Seems like a perfect cloud for a sunrise/sunset imo, so maybe you can put that in there somewhere?
i didn't know what this was until i saw the title.. xD it looked like a lump of some kind of dense liquidy slop substance.. kinda ..
powdery at the back and gelatinous at the front..
lol.
I feel like it needs something more to put it in context, maybe a horizon or some more clouds behind it?
There appears to be a nuclear meltdown beneath it. Could use a bit more contrast in my opinion.
