It looks to me like you didn't commit to the forms as much as they required. Everything looks mushy and under-defined except for the lower eyelid which looks appropriately definitive. So you started in the right direction but didn't quite finish the job.
In short I recommend you spend more time committing to and refining shapes. You've shown that you know how to do that with the lower eye lid. Now just apply that same attention to everything and I'll bet the final looks a lot better! 👍
Thanks u :D, i have been learning for 2 weeks but everything seems not so good, i still cant scuplt any creatures without tutorial, i dunno how can i be better, maybe my study methods is wrong ( can you give me some tips :((( ?)
Becoming an artist takes time. You have got to pay your dues. Go over to Reddit into any of the art related rooms. People post one year comparisons. You will see how much a year of consistent practice can do.
I agree with mrorangekitty , it is a process and it takes time. Keeping motivated is key, when stuff becomes too hard and I get demotivated, I always jump back to other types of smaller 3d projects (Low poly, a basic object, another exercise/tutorial) .A little win here helps build confidence, and subconsciously, grasping some extra understanding on how blender works.
Give yourself the time and enjoy the ride 🙂
Thanks you, If i hadnt seen these comments this morning, i would have dropped Blender and moved to other stuffs. Your comment motivated me, because i always felt myself as an idiot when i failed on something ( i'll keep practice it now, thanks you a lot, sorry for my english)
Glad to read this! happy to see your work evolve in the future! and no worry for your english !
