Hi.
Just keep on working on it. Get as many reffercnes as posible and dont add detail till your realy happy with the base sculpting. Its a good idear to add high detail to a layer, easy to switch on and off.
Just a few things:
Spend longer at Sub D level 1. In this level you want to get the whole base shape as well as you can. Each level needs the same attention, use each level to your best. This includes directing the flow of the major form at a early stage.
Work on the ears at a much earlyer level, dont neglect any area, try to build it up equaly. Your find that if you work on this basis the model will look consistant in its flow and form.
tez thanks for advises. the ears will not be visible because of the armor and i’m not bothering to mes with them.
