How can I improve on these?

Hey everyone. I was hoping I could get some feedback on how to improve these images and possibly what their strengths are. Thanks for your time.

hey those are nice
i espicially like the shoes done in ink
the only comments are the trees on the house i think they are a bit rushed
the boxes i think that they are out of prespective
thats all i have to say

I could almost bet my money that the shoes are drawn by a different artist.

You need to make your lines straigher and your circles rounder. Also need to make your line width(s) more uniform.

On the box and the plate drawings, I cannot decipher the light source that will cast shadows as you have depicted.

What is the long thin strip standing in the box drawing? Looks like a large envelop.

Cheers.

Thanks for the feedback guys!

The shoes are my own but I definately put more time into them than the other pieces. The small box with the strip was a US postal package...just wanted to add a bit of detail. Anyway, thanks again for the comments.
