hhrrrrr. actually I wanted to practice perspective, but I don't know why I ended up adding so many randomness. (whales, rainbow, etc) and lately there are so many Grab My memes on dA, that's why I put that rainbow =w= (which makes it so weird, I know)
Mosobot64 here agina folks, reporting to you live from a strange dream. I can't tell you whether I'm above the clouds or below the waters. Oh that .
Well, first things first, My mind has been blown. Like I said before, the arrangement of elements give me the impression that I'm above the clouds and below the sea at the same time. It's like I'm in Atlantis and Valhalla at the same time. Oh, and that city's moving, too.
The only criticism that the city below doesn't seem to be rendered with the sort of depth that the elements above are. It seems, dare I say it, flat. Also, bit of atmospheric envelope painted it could induce even more vertigo.
This in itself is a truly lovely piece, and I take my hat off to you, but something that bothers me a bit is the perspective between the floating castle and the one below it. The floating castle has depth and is beautifully 3D at a slant, but the castle at the bottom of the picture throws you for a loop by going back to 2D. The picture itself would have been stunning even without it, giving you the feeling of being completely in the air, rather than on the ground with the other castle. By the way, LOVE the whales and rainbow, and the whispy clouds add a great mysterious effect like you're also underwater.
Honestly, in this instance, in my opinion, the rainbow really works for this. If it wasn't for that,, the flow of this whole thing would be lost, at least to me. What would make it better, to me, is getting rid of that "randomness" that you mentioned before, change the perspective of the castle to a descending way like it's crashing down. I hope that works.
I love how the color scheme and way you painted the sky make it look like both waves of water and swirly clouds. Placement of the palace soaring high makes it seem like it is ascending to the heavens or just goin' on some awesome adventure. Amusing choice of title by combining "insanity" and "imagination".
