Hi Lore23, welcome to RetouchPRO
Hope you enjoy your stay here and make lots of friends. Poke around, ask questions, take part in some of the discussions, challenges, etc., have fun!
If you use Photoshop you can post fairly large pictures which are under 100k using the 'save for web' function in Photoshop as described here: Size, Quality and/or Format your Attached Images.. (Click here
If you want to post a larger resolution that is over 100K then you can host your image elsewhere and attach a link in the thread, but also
please attach an under 100K version (so the thread remains useful in the future, regardless of external links).
Other Hosts if you do not have your own site: ImageVenue.com (3Meg max, free) pixentral.com (2Meg max, free) photobucket.com (1 Meg max free, 5 Meg PRO) mediafire.com (100 Meg per file, free) post a link in the thread to the site that is hosting the larger image.
The image you have posted is very small... If it is for a Photography assignment then the object should be to get the final image you want in camera. No retouching should be needed.
One question to be answered is.. What is to be the focus of this picture?
below is just a suggestion for the small picture
