I fast was growing bored of the humanoid side, so i decided to try something abit more monstrous, i went back to the 4 large spiked legs as these seemed the least humanoid that i drew.
It also has 2 sets of arms now, a smaller set about halfway down the body with human like hands for grabbing and a larger pair ontop of the shoulder, these have rather large spiked pincers which act as weapons for hunting or defending itself from attackers.

I also dropped the armor and tried to focus more upon the exo-skeleton that insects have, it didnt go that well as it still looks like its wearing body armor.

In the end i just went for a complete monster, all humanoid aspects have been completely lost.
I already liked the design i had and i didn't really want to change it, but there were a few issues like: how would it grasp things, the tip of the tail, what is it for? and skin, what kind of skin would it have, so i had to do more iterating.

I didn't really know what to do, most of these are just more weapons, in fact i went a bit OTT on the 4th one, for some reason i had the urge to graft a laser cannon on its backside, but if i did that i was going into a territory i don't like, so that idea was out of the way.

The first 4 drawings on the left are basically just spikes, one of them dripping a acidic compound, i guess they would be for impaling prey or injecting venom or something.

No you are not seeing things, i did draw an eye on the end of the tail, im not sure why at all, it was just a spur of the moment thing and yes the one on the right of it IS a mouth. I didnt like that idea as soon as i drew it, perhaps it has something to do with the thought of it eating through its uhm...ass.

The top 2 on the right are basically just weapons, im not sure how the flail would work, as it would have to be rather heavy to cause some damage, but the connection to the body would have to be rather flexible to swing round, but then it would just break off and cause damage to itself...
The spiky tail was inspired by a stegosaurus, as there tail was the same, this one was most likely just for show. Im also not sure about the bottom right one, its too weird...

God! The claws were the most aggravating thing to concept ever!
It was just the same thing over and over, i wanted to keep the pincers for there crushing power, so i pretty much just tried aesthetics designs, adding crystals that are growing out of the "skin". I tried to venture away from pincers a few times, the 2nd on top row is like a scythe blade and would just tear flesh from bone. The middle bottom is just a spike, made for impaling and causes lethal damage fast.

I decided to go with bottom right, its 4 fingers which are pretty much blades, they allow for grabbing, although they cant bend like normal fingers. There also super sharp! A slash from that hand would probably leave a large groove in your bone, if not go straight through and take the limb off.
