i started also thinking that the model is little bit boring
This echos my only criticism so far: There’s a lack of detail. Proportions are great and the overall structure is spot on. But it’d be a much more interesting model if there were wood splits, bevels and dents on the edges. Currently it feels like a work in progress rather than a finished model ready for texturing.
I’d like to see you tackle those details if you’re up for it. This video should be especially relevant to the task.
