Whoa, didn't know you can help newbies display their images! Thank you!! Also, oops, my bad. I literally thought just the image url has to be correct. I just checked the formatting and saw my mistakes. It's fixed now I think.
Now is better. Your samples are now visible to all. you can always learn something new

btw. Your work looks great, I like it. Probably you can think to participate in Roobet digital art contests mentioned by Insanerman. seems like a good opportunity for you, although I have seen some very good works there.
