It puts a smile on my face to see so many entries! Now then, to critiquing!!!
Raindrop14 - I'm with Xin on this one, I couldn't really tell what I was looking at when I saw it. Perhaps if I had remember Collin I would have known but I didn't so.... I didn't.
De-krumple - I love this! The idea was simply fantastic and amusing. My favorite part is "MIDNA!!!... Not midna." That is hilarious. A little nitpicking now, you've made TP Link's hair a little too blond. Also, the theme you've chose leans more into Majora's Mask than ocarina of time.
Xin - Art made by Xin... do I need to say more XD. Anyways, once again Xin your art is fantastic. Literally, when I chose this theme, I sat down and said... "Hmmm... I know! I'll do a pic with Midna and Navi and Midna can be holding a fly swatter with her magic hand. *Thinks for a second* Naw, I'll do the sidekick exchange idea." So you can imagine my surprise when I got this entry. Because I thought that, the pic seems a little less original in my eyes but that's cause I already saw it in my head a couple of times. Also, Navi WATCH OUT!!!
Random Person - Your art sucks. I don't know why you keep entering.
Mandy - The art and idea are nice, though not my favorite. A couple of lines that should be straight are crooked and the outline seems to fade in some places. Zelda's skin is fine but Link's is a little pale. Try adding some pink to it. I also agree with Xin on the expressions. I do however like that you used the mirror shield which is a better indication of which Link we're looking at, and Navi's statement is very funny.
And Xin gets my vote yet again. One of these days I'll be able to vote for my own pic over hers, but until that time, I am forced to root for the enemy.... duh... I mean... competition
.
And a totally random side comment: Midna's helmet designs...AURGH!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! ...yeah
Yeah... I saw that and was like... sorry Midna, you're a shadow so you're not getting that much detail XD
