Ok things that you made wrong and
1. Never use racealias as ohter races got if you have edit something.
2. #Blue isnt a color that can be used
3. "start with nade|Big Boom|Type !he for nade!| Blow up on death" is wrong it most be "start with nade|Big Boom|Chance to slow down enemy with nades|Blow up on death"
4. Skill 3 can also be activated with knife, and its overpowerd
Your race only got one Not Copy Paste skill, Ohters is copy and paste. Your race is more Copy and Paste than custom.
First Skill - That looks good, not overpowerd
Second Skill - Looks also fine, Copy and Paste, not overpowerd
Thrid Skill - Looks to overpowerd with the time it lasts per lvl, Copy And Paste, not only for nades
Fourth Skill - Looks fine, Copy and Paste, not overpowerd
But its still a good race. Change the thrid skill to have lower duration and all should be fine, + edit the text in player_spawn_cmd to have #Green or #Lightgreen, #Blue isnt able, Change description, and chance the racealias names then race should be a good race, no need to chance in Skill 1 which actually looks pretty good.
