Speaking from Newbies point of view maybe this could help with some inspiration.
With character concepts, Think of your own personal playstyle, Personality, Background traits that you have always enjoyed doing.
Couple that with classes you would personally enjoy exploring, A good method which I do myself is reflecting into 3.5 source works such as (And definately not limited to):

Players Handbook 3.5

Dungeon Masters guide 3.5

Libris Mortis

Book of Vile Darkness (Although warning there are some adult themes there but very good for blackguard and warrior of darkness themes fitting in with this server on a PG 13 scale.)
Another good way for inspiration is also the profession of the character, Imagining on a day to day basis what she/he would do. Funnily though, If hunting is your thing like you mentioned you could keep a journal of encounters and empathise from your characters perspective in bright emotions, Colours, Smells and really tailor the experiences to you.
Otherwise a popular profession in DnD is being a merchant, My partner in crime is interested in the Master Achemist class but coupling on the ability to enchant/Craft Arms, Armour, Wands and potions alike.
Again, I speak from Dnd experience from the past and not from the server but by what limited experience I've had here so far, It seems it would be the best platform for you to explore what you always wanted to, Irregardless of mechanical sense of builds.
Hope this helps!
