Hi…HladekStepan…
LOL…
…There are no losers, or loser threads in this forum…everyone in here is a winner…
We are all at different stages of developement in our knowlage of art. The only loser that I can think of, would be someone who thinks that they know it all.The more a person knows about art, the more they should realize, that they know nothing about art.
It’s that realization that keeps the journy alive, and makes it an adventure worth traveling, and exploring…:bounce: 
I like what you did with that hand…now, if you want to take it further, you could do what Caravaggio would do to it…bring the parts that are closest to the viewer into focus, by bringing out the details,…harder, more defined edges, and interior surfaces, ect. and leave out more and more details as it recedes into shadow, and becomes vague and softer.
I also like the way you painted that Goya painting…my favorite artist of all time, or at least one of them for sure.
If you like his work, you might want to take just a small piece of one of his paintings to start with,…maybe a hand, or face even,…and see how close you can come to reproducing it.
This is a GREAT way to learn and advance your knowlage…just take your time, and really take the time to see every little detail that he put into that hand or face.
When you do these exercises, all that little information gets recorded and trapped in your memory, and will show itself in your future works, making them better as you go forward.
There is no magic to it, …It is just a matter of learning to see, and using what you have seen, on what you are creating at the moment…
Hope these words help you, …and don’t ever or even be intimadated by anyone on this forum…MYSELF INCLUDED…We are all in the same boat here, and we are all here to learn.
You and everyone in this forum, are always welcome to state your opinions, views ect. concerning my work or whatever in my thread…I DON’T BITE, MOST OF THE TIME ANYWAY…LOL:scream:
TAKE CARE
