Place shrimp in a bowl with the juice of 1 lime, garlic powder, chili powder, cumin, and salt and pepper. Toss to coat them. Let sit while you prepare the salsa and crema.
Peel the peaches and then chop them along with the tomato and peppers into bite size pieces. Put them in a bowl. Add corn. Add the juice of half a lime. Set aside.
To make the coconut crema, whisk together the sour cream, coconut milk, shredded coconut, lime juice, and honey. Set aside.
Heat a grill pan over medium to medium high heat with a tablespoon of coconut oil. Cook the shrimp for 2-3 minutes prior to flipping and cooking an additional 2 minutes.
To assemble the tacos, place 3-4 shrimp in each corn tortilla. Top with the peach salsa and coconut crema. Garnish with shredded coconut and fresh cilantro if desired.
