Just beat 4th Gym!

I have just completed the 4th gym and my team currently stands as:

- Feraligatr - Level 31
- Onix - Level 34
- Hypno - Level 27
- Kadabra - Level 22 [would appreciate if someone would trade evolve for me]
- Sudowoodo - Level 24 [not really sure why, just to fill a slot]
- Vulpix - Level 27

Any feedback and advice on the quality of my team and any ways to improve will be appreciated greatly!
P.S Please do not flame my team, I just started this game...
