I'm not sure that really make sense for the pilot to have to crawl and squeeze into the tiny gap, instead of been lowered through the sizable hatch in the top. I'm not saying your wrong but it just doesn't make much sense to me.
On to the MOC Well Done markstones at the start I also thought it was the Lego version. The back, and front are really well done, as is the interior, however the wings look a little off, its that gap between the sloped wings, and the straight wing, I don't know how you would address it in Lego, but that it as far as criticism goes.
