Oh I would never do that my friend, it's just that I'm always looking to feature great superhero art in my blog to support up and coming talent like yours (you can see it here [link]) I know it may not seem like a big deal, but I also have a policy of zero watermarks unless it's a personal sing from the artist, your Avengers poster is amazing but the DV watermark totally ruins it, a personal signature in a visible place could do much more, but that's just my opinion.
before I didn't put the watermarks there but now I saw hundreds of people are taking my poster and changing them or taking all the credit. It made me mad that my posters are all over the web but nobody knows I made them. So now I put my watermark and everything just to be safe.
U makes great fan-posters but watermarks ruins admiration of its. Besides i cant read your nickname on it. It's too much transparent. If u really wanna fame u can put something like "Fan-design by DiamondDesignHD" under movie title. It would be more intesting, informative and looks realy harmonic versus actual version with standart DA watermark.
You have great style. Keep on going forward
