New old Cover Lineart

I found this new-old Cover pic in my "Mechas Heart Folder"...
It's been a while... where i saw this pic...

This should be originally be the new Cover of Mechas Heart, but now after so many changes inside the story i must made a new one hehehehe T_T

but i'm sure the next will be better than this one XD (at least i hope so)

There still a lot of mistakes that i didn't correct...
