That looks a bit girly for him, plus where's his other arm on the walk frame?
I'd base Siarnaq's frames a tad off the actual game as well as a bit of Shadowman if needed.
To tell ya the truth the Siarnaq one did catch my eye since it was a skin I had planned in the future but haven't had enough motivation to make it just yet, if you want to see his sprite here it is:

It's not all that great, I kinda planned a revamp to this sprite but I haven't bothered with a skin yet and haven't had the motivation to fix it up so if you need this for reference by any chance to fix up yours, go right ahead. Just figured I'd show you this due to your interest in Siarnaq.
Also why is it everytime you post it's of a completely different skin? You're not gonna get work done if you just keep adding on to what you want to make, unless you're like me who gets bored of working on a single skin for too long therefore need a couple other things to fall back on in case but this is getting a little silly at this point.
