Welcome and good of you to jump in posting an old build. Looks fine and is unusual subject.
Regarding "not up to great standard". The "fun standard" is paramount. Point of OOB and kitbash builds is to enjoy it, is to have fun doing the build.
Aint a job, is a fun hobby. One that we share common interest in. Always interesting to see what other folks have built or are building. In pictures and plastic.
I find that figuring out a kitbash. Configuration and what parts from various kits it takes is same fun as building.
Browse through prior year postings, see whatz been built.
