In terms of an acceptable sheet, a lot of that will depend on the GM of a specific game, as well as your own personal preference. For example, I need some central place to get critical things like feature descriptions, base saves, and skill values. Now, if you want to just list out the names of features in the "Notes" area, that's fine, I can do the legwork to look it up in the books themselves. However, if you'd prefer to not bounce all over, by all means, use the "Feats/Abilities" area to document more completely.
Brainmush here is an example of how I typically set up my characters.
Were I to be evaluating the sheet you presented for one of my games, here's the feedback I'd provide (nothing meant to be aggressive or offensive, just the collection of thought):
Your Proficiency modifier isn't filled in. At level 1, this value should be a 2.
Background isn't indicated anywhere.
Total HP is way too high for a level 1 with a 9 in CON. This should be 9 HP (10 for ranger at base, -1 for con mod)
Temp HP should be zero as you have no source of those listed.
AC is missing entirely.
Init bonus should be a 0 as you have no bonus to DEX.
Speed should be 30 for a human.
Longbow stats are slightly off
Spells are not correct
Now, part of this may be that you haven't gone through the full creation of a D&D 5e character before. Do you have access to the players handbook (in some form)? It is likely more useful to go through general character creation for D&D before tackling how to enter that information into the website. :)
