Here’s one I did of Tom baker (my fave doctor)
Small criticism, the image you used for the TARDIS does not line up with the Doctor at all. The exterior is the original Brachacki prop, used by Hartnell, and while Baker did use a version of the Brachacki prop, it was essentially an entirely different object by then due to parts being replaced. Only lasted one story with him before it was replaced anyways, iirc.
But a slightly different note, I'm not 100% sure on the legality side of posting edits like this, but taking someone's base work (direct link to DomGreenDesign's Baker art) and then overlaying a different image over the black bit seems a little bit iffy.
But legality and accuracy aside, it looks fairly well done in parts, although there's definitely some weirdness with the blurring on some edges not being quite up to scratch with other bits. Might've been a better solution to key out the black shadow from the initial art, and then just put the galaxy behind it, sort of like putting a cutout or sticker on another bit of paper.
