Hey Mirek
Dont be like that, this is looking good, ive not critted as I've not seen anything worth critting!
Sometimes if nothings wrong then you dont get crits, dont take it as no ones interested, you could take it as everytings fine with it!
When you move from the modeling phase to the texturing rendering and a backgorund scene, and animation (if your going to do that for it) i'm sure that you will get more crits and comments.
I was going to say that the other day I saw a really strange small, old car parked in Manchester, wish I would have had my camera on me as it would have made good ref for another model in this style.
