I see many nice ideas here and really good approaches but IMO you have to concentrate on anatomy now. Read some tutorials on anatomy (example: http://warrenlouw.deviantart.com/gallery/#/d2p3au1) and make simple sketches with pencils to get used to the human body shapes.
Keep on drawing, looking forward to see more.
Look at insects maybe or even look at medieval armor or samurai. there lots of reference on the web i mean sometimes a pattern for your armor could come from finding a few unique shapes from the objects around ur room. For example, the button layout on your monitor mixed with the pattern on your curtains, or the vent on your house wall. Hope this helps
Lots of work but not much studies? you should try do some and post them
I Keep sketching (with pencil and paper).
This all above painting are my study, can U all comment on them , where am I lacking in them ?
If I would say this is my product, believe me none of you would be able to say a bit of mistake in it.(Once I am a master , till I a'int).
All this one are my study, Comment where am I lacking in them.
For example Tell me that the samurai Armour is lacking specularity to be gold. Tell me use hard tone brush for sharp specular , rather than telling you need to study. That does not make sense, where am I wrong ?
I may sound harsh but believe me u Join a forum full of artist , none of them is able to comment where am I lagging in the painting I make, they instead tell you do some study. What to study , no one tells me?
They say improve anatomy, they cant say where My character is lagging in anatomy.
that all for now, please comment only if you wanna comment how I can improve my existing art
I think you should try to do value studies unless you're already working on it. I think that would help your paintings
So, when people offer the advice to study more - it isn't meant as a throw away comment but is actually the only way forward. Get some good reference of what it is you want to portray, then draw it over and over until you are confident. I would really advise finding a life drawing class with a decent tutor - learning the fundamentals will allow you to enjoy Photoshop / painting / drawing a whole lot more.
Hope that is more the kind of constructive criticism you've asked for?
No worries. Posting your progress here will surely help, as I've been around a while and never received an unhelpful piece of feedback. Perhaps rather than thinking of it as 'study', consider what your favourite subject is; research it then draw it many times from reference. Consider which artists are your favourite - I used to copy my favourites to death, as I loved their work so much. Take from my advice what you will, that's just the way I learned...
