First off, let me just say that I really love how you've put this together - like, completely. The folds in the fabric look gorgeous, the light filtering through the window ... my jaw dropped when I saw it!
The only thing I'd suggest working on is the text draw(?) on the wall - it doesn't look like it fits onto the wall that well (best example would be the 'soooooooo sexy' that goes across the left wall and the back wall or the red balloons - maybe try the multiply effect on the red to make it look darker and more drawn onto the wall?). I'd try using a different more rough brush for wall text, kind of like the crayon brush on SAI just to make it look a little more fitting with the image.
Other than that the detail in this is amazing. It was only a matter of time before Pilot was going to write a romantic novel about him and Captain! :3
Esta loquísimo xDD es un caso de manicomio, me encanta este tipo de personajes xD Tiene pinta de que te lo debes de haber pasado teta escribiendo todo lo que hay por las paredes : ) Buen trabajo con la ilustración!!
The notes are a lot of fun, but I think my favourite was the face drawn on Snippy Awesome picture! You requested critique (but I'm scared of the new dA formats, so it's just going in comment form) so I would suggest perhaps cropping in the top and bottom of the image just a little to make it a more focused piece. You only really need just below the knee to show he's sitting, and although I really like the peeling wallpaper near the ceiling, I think the shot as a whole would look more aesthetic if it was just a little less tall. Great stuff regardless of whether or not that's relevant, and it looks like you had a ton of fun making it (which is always important )
So crazy, yet so awesome! 8D I love all that notes on a wall, they are so psychotic and in-character (imo Pilot acually thinks that way all the time). And a reference to The Twilight is just... xD Brilliant work!
