Looks good! Sounds like it was a lot of work.
It’s also clear that you have learned the important art of heromachine smoke and mirrors. Covering the messy parts of a design with clothes, foreground objects and masking is a good, powerful option. The next step is to learn to see when that is necessary in advance, before spending a lot of time trying to fix the unfixable.
The cart looks great! Really good use of all those parts to create an impression of three-dimensionality, the chest was a nice addition. Heavier shading could help emphasize the depth, but that’s a slippery slope.
Nice work, all around. I’m looking forward to seeing more.
