Yamada GMP

Hello. Umm, i hope i wont offend you, but i think that this particular design needs reworking, as is it will be dangerous to shooter, and probably wont even fire.
Let me try to explain what i mean. Firstly - there is a reason why casings fall down on P-90, its because ejector is so close to shooter that if casings will be ejected sideways they will smack him right in the face.
And other thing is the ejector position on the gun. Its really too far than it should be. Normally the ejection window is at same spot where magazine is, cause casings have short time before they will be ejected by the bolt going backwards. In this case its high posibility that it will simply not eject at all. Sure, i guess you can come with some workaround, by why make it more complex ?
If a may, here is my suggestions on how to make it sustainable. Either put ejector closer to mag, or make mag longer, so that they allign, this is one option. Move ejector down isnt neccesery, its will still function, howewer shooter will be able to hold it only on one side, cause casings to the face.
Or there is another option - simply make it fire caseless ammunition and remove ejection port at all, you wont need it
Hope you dont mind my criticism, not hatin, just my thoughts, i really like the overall shape and stylization of the gun itself, and its description aswell.
