Ok, that's a good start Fire. Your skill has to all add up to 100. For example, if I was writing the bio of your wolf these are what the skills might look like.
Skills:
Strength: 30
Speed: 40
Agility: 10
Wisdom: 20
That's just an example, see when all 4 skills are added together, they equal 100
As for adding a picture, you put the link of the image URL in the blank box like in the picture below:
[Only admins are allowed to see this image] The button you want is this one
[Only admins are allowed to see this image] Once you put the URL into that black box, press the purple "Ok" button.
If the image you want to load is on your computer, you can use this site:
[Only admins are allowed to see this link] then choose the top left format for your image, I think it should be "Convert to GIF". Wait for it load, then click your image and copy the URL, the final page should be white with just your image on the top left. Hope I didn't make it too complecated. Once you see how it's done, you'll see it's easy
Don't worry, ask again if something went wrong.
