My First Kit-bashed mech

So recently, I had tried kit-bashing pieces to make a mech. this was my first time doing so and I think it came out okay for a first time. I’d like to keep doing this since this time was so much fun, so I’m asking for anyone to please give me feedback and responses on this so I know where and how I can improve in the future. Thank you for your time

Behind the mech:

I think you need to detail the big piece more its realy low poly looking compare to the rest of the mecha. Especialy the central part.
