The shadow looks uneven, and the rat does to... but nice work anyway! ^_^
Pretty sure I've fixed the stuff you mentioned. Thanks for the idea with the text
Shadow is cast in front of the TV 'cos of the light from the TV but everything else's LS is from above-slightlytotheright.
I'll fix the arm and hands, probably shouldn't have used my (bandaged) non-pixelling hand for reference XD
Text says "Winner Location..." but only the capitals look like their respective letters :P
You've used the palette well - as per usual, I love the ugly wallpaper and the antenna dome thing looks great.
Your shadow(s) still makes no sense. Where is/are your light source(s)? Your host's arm is llooooooong. I know hands are hard to draw, but I reckon you have the ability to improve them a bit, right now they're a bit lumpy.
Oh and clever use of the coloured squares on the ticket :D I didn't even notice they represented the numbers until Oren mentioned it. 
What does the text say - Wat Luck?
@oren, x-death, Manu: Thanks :)
@Dex & Manu: Agreed. Edited TV shadow, hands, ambiguously gross puddle. Added rat.
you used the palette well!
i agree with manupix though, and i'll have to say myself this looks very flat; it looks as if everything lies on the same plane, and that's not a good thing
this probably wasn't the best angle to choose, because depth is harder to portray straight on rather than other ways, but either way nice work and good luck in the challenge, bro!
Very good palette use!
The tv should cast a shadow on the wall too, would be better for depth; I don't get the shadow on the floor (guy's shadow?); hands look a bit weird yet.
Oh now I get it! didn't look on the colores that are on the paper :P
@JoCh: He's really poor. There's only one channel *SHIFTY LOOK*
@j0k3r: Thanks :)
excellent, good idea ! But i thing that the tv screen is a little bit strange it's a mix between a old screen of the 60's and a flat tv of now days, and there is not boutons, why ?
my vote again
