Manuel...please...no need to feel that way. For lack of motivation and inspiration, you continue to produce great images loved by so many of us, and for where your work is going, consider this period of time as the experimental moment and you'll soon discover where you want to be. Just don't create pressure for yourself...I say this from the heart...cus I value you and your work.
That's alright. All that means is you can seek new inspitration from anywhere really. How does looking at something new or even old make you think or feel. Then from there all you have to do is find a way to translate it into the language of art.
I'm glad to hear that. (: Just be confident in where you're going - even if you don't like it now, it's all part of the improvement. One day you'll look at your work, and realize, that this is what you wanted to do all along.
