Soo here's a lineart i did x)
at first i just wanted to sketch it digitally and do a traditional lineart.
But some parts just hard to be done very detailed and thin and that would not be possible with a fineliner x.x
sooo you may wanna try and give him some colors as well (?)
anyways here's the HQ-Link:
