>any good pointers on how to create one from scratch ?
Learn the basics of blender, I guess most people would recommend the donut tutorial nowadays

Then learn about character modeling by following tutorials, studying existing models and especially by observing how other artists are working. Start with low poly stuff (like https://www.youtube.com/watch?v=yx5RCacof1s ) and work your way up from there. I can recommend Daniel Kreuter's anime character series on youtube but it's pretty advanced stuff. https://www.youtube.com/watch?v=5Xuf6ODN_xY&list=PLvgIVNDU-Dxjb3eukDF5W0l0-6ShO9OiM
The most important thing is to practice a bit every day. Use good references, always try to start simple with the least amount of polygons possible and add details in layers as you progress.
It's pretty time consuming and frustrating but if I managed to do it then so can you.
