Modular engine

I was trying to make a chainsaw from a game but the result was not very satisfying. However, I am quite happy with the engine for the thing.
Using sketchstyle addon, mostly default settings, I was able to make blueprint images as a final product.

I was having trouble with software performance as I was trying to bevel everything and the polygon count rocketed.
I realized the importance of a 2D sketch which was absent in this project. A plan would have boosted speed and performance. So that’s a lesson learnt.
Hope you like it and please give any advice, I am very willing to discuss and learn.
Thank you very much!!!
