You don't even have all your defenses and troops fully maxed... Why are you asking about the walls???
Don't upgrade yet, you'll regret it.
Those people telling you to upgrade right now, they tell you that because they want another rusher in the matchmaking queue so they can easily steal all your loot because of your weak defenses and the loot cap (They are TH9s and 10, and when you upgrade to TH9 they'll be able to steal more loot from you)
First, max all your defenses (even bombs).
Max all your troops (DE troops also)
And then, you can upgrade to TH9 even with purple walls.
