You average 5.9 CS per minute as Mid; Emerald players average about 6.8. Every 15 CS is roughly a kill worth of gold. Practise last-hitting under tower, shove the wave before recalling, and catch side waves between fights instead of standing in lane doing nothing.
You take part in 35% of your team's kills; Emerald players average 56%. After your first item, look to rotate for dragon, grubs and herald, and keep Teleport for fights rather than for farming.
You spend 11% of your games dead. Late deaths cost a minute each; when a fight is lost, back off and defend rather than adding one more death to it.
