awesome work dude the top one looks like a zerling or sumthing since she looks more like a mutation for self-breeding than a queen also the bottom one is very cool more like the alien series but it seem i can't keep myself from drawing a cat face on her nevermind that your works is awesome make sure you don't see this on mass effect 4 without getting paid or something
also you you give a little love to the metroid series o will be very thankfull since nobody does care about all the stage of metroids except for lava one(the jelly-fish like)

They're both awesome, but i think the bottom one seems more alien like. Still, the top queen looks good for a game where you kill mutated animals and stuff, then you have to make your way trough a cave full of giant mutant insects and that is the queen who's waiting deep inside the cave, producing more and more children, feasting on the corpses of all who comes near the cave, every prey unlucky enough to be caugh. What do you think, Sev4?

The bottom one's neck, arms and head remind me of the Alien Queen from Aliens. Besides that, the top one looks like a reptillian insect somehow...

has a preetty good style of the detail

I like it, thou the blue one it's more alien type, the first one its more like bug type :D u choose the right concept!
