thank you takashmen for coment.
I watch your pieces and i have to say that there are grate stufs. i like de environments. It's nice.
I hope my advice for watercolor could help you!
The procces of water color is little bit dificult for me to explain because of my poor english but I'll try for you.
The paper: at first you have to sumerge the paper into water for 10 to 20 minutes.
After that take a frame (canvas?) and paste the paper in it with white glue. The paper should be still wet.
Then you have to straighten out the paper to fich it as much tense as you can.
The painting procces: There are some good ways to paint. The first skill you have to learn is to paint a non degradate surface. It's posibble only if you do it little by little. You should draw a horizontal line with water color.(wet line) after that extend this line to botton more or less 1 cm. after that take painting again with the brush and repeate the process. The procces for degradation is the same but in this time you have to add water in your color little by little. (or adding an other color to make a mix).
WOW I hope it helps you. It's little bit mess
