Honored to find out this morning that my #skrull designs were shown by the #mcu at #comiccon2017 At first I was afraid that the artwork got leaked and I was a bit panicked, but fortunately it was done on purpose :-) I did these designs while working in house at #marvel on #captainmarvel for the very talented @andyparkart You should all check out his Captain Marvel design. It was also released and is amazing! #marvelcinematicuniverse #marvelmovies #marvel #skrulls #superskrulls #aliens #badguys
