"Build Failed" :app:processDebugResources FAILED

Every time I run this app it makes me lose my mind, I have no what's going on.

Android Studio has updated since Ben did these vids, I have added my own images with the same names and resolutions as Ben's mockups (to create my own interactive story). Placed the icon images into their respective mipmap folders and did same with the drawable folders. It's been a week and this just refuses to run and ... I think I'm going insane lol

Here's what is says on my Gradle Console

:app:processDebugResources FAILED

FAILURE: Build failed with an exception.

• What went wrong: Execution failed for task ':app:processDebugResources'.

BUILD FAILED

here's my build.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.3"

    defaultConfig {
        applicationId "kpqventures.wordpress.com.kpqinteractivetourapp"
        minSdkVersion 15
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.2.1'
    compile 'com.android.support:design:23.2.1'
}
