It looks pretty nice. Could probably use more scenery and some shading on the gray bottle parts on the sides, but I absolutely love your shading technique on the cap. What you've done with the lower part of the map looks pretty awesome too.
Overall, it's a really nice map. I can't say much for the gameplay as I haven't tested it, but as long is it isn't insanely small or large it should be alright.
Good job, dude!
