Welcome to the board billaaa777
1st things 1st - those aren't "galleries", they are "Free Sites"
Site 1 - like DallasDeb said, the pics are a tad bit too big in file size. Also, the last pic on galery 2 looks very out of place, since she's getting naked in 1 thru 9
Site 2 - More & more Link Lists are not accepting vid caps for the cotnent, so you might want to check their rules before you submti those (if you haven't already)
Site 3 - the ad on the top right of each gallery may be coinsidered a blind link because it does sorta look like a thumbnail with the legit thumbnail sitting next to it on the left.
All in all, the sites are rather good for a self-proclaimed newbie, just need a little fine tuning
