If i'm seeing it right from stats at level 1:
Flat Armor yellows
I still prefer Phoenix Udyr over Tiger as it gives you much better clear speeds, and allows you to build tanky while still doing damage. With this, if you started at blue, you could get to their red much faster (as Malphite is such a slow jungler) - You would've seen Malphite run passed you with little to no health and still secured the kill, and still have the experience/gold from your red buff if you followed the same path and died bottom (ganking after killing Malph) - As you did it, Malphites red was left up, allowing him to take it for the experience/gold chunk
Other than that, you ganked lanes that needed it (although you could've dived top very easily to put Tristana massively ahead - Gangplank was level 8 to her 11, and was at 21 CS at like 10 mins) but controlled your own jungle well, as well as theres.
I don't think you needed to Tiger, as you had 2 forms of AD damage (Tristana and Miss Fortune) but had no tankiness up front. If the game would've gone longer, or the lanes played out differently, I think that could've punished you. Boots > double gold per 5 > Boots 2 > Aegis/Wits End and then Tanky from there will make you a bear slapping machine in team fights.
Skill order, I think you should've gone bear > turtle as you had lots of sustain from Wriggles relatively early, and bear would've made gap closing so much faster/easier.
You played really well regardless.
