I can't add much to what else has been said, apart from this. The vids don't sell you.
Yes, your playing is solid and competent, fine and ideal for the music. But the visuals aren't. You don't need to jump around, but maybe you should stand and just look more engaged.
Does this guy look like he could do the job and keep his energy levels up for, say, two 90min sets? Because that's what the band needs! I'm not sure your relaxed sitting position does that for you.
Keep networking though, and keep trying!
Cheers!
