About the Hd thing. It really shouldn’t happen. If you say that you did it on photoshop make sure you are using 300 or 600 ppi/dpi. Flowlab will use its Anti-Aliasing feature and make it look super sharp as you want it.
I talked about this on the second page of Affrayer’s discussion:

It will never be 100% vector (i mean, you did it on photoshop and photoshop works with pixels, that’s why I meant the 300dpi thing) but you really get a close result.
