You were so excited about being here, to do some writing before starting school, if I remember correctly. I think I commented on one or two of your hubs, but can't find them now - I guess not visible if need revision.
If I remember correctly, although you had some great ideas, the text content was not all that long, and some of your large pictures were pixelating - this is due to the original size of the image being small already, so when they appear large, their quality is lost.
Don't give up!
I suggest look at your articles again, perhaps add a paragraph or two to each, and use the "shift to the right" green arrow key in your image capsules to keep the images smaller - also select "quarter size image" in the image size section of the capsule, and then try and resubmit them.
I hope that helps, as I look forward to seeing you stick around on HubPages for longer. Good luck.
